it thus is important and general object of the present invention to provide a new and improved window assembly having tightly positioned but tiltable sashes the in to facilitate access to the sashes for any desired purpose.

Another object of the invention is to provide a novel improved window assembly where the window sashes are releasably and slidably positioned therein and where one sash is wider than the other but where both sashes can be conveniently tilted out from the remainder of the ass bly so that the sashes can be cleaned, repaired, or th like.

Another object of the invention is to provide a novel and improved window assembly where the wind w sashes are releasably and slidably positioned therein and where one sash is wider than the other but where both sashes can be conveniently tilted out so that the sashes can be cleaned, repaired, or the like.

Ft ther objects of the invention are to provide novel and improved track members for slidably and removably receiving and positioning framed window sashes therein; 7 e special lateral y movable track members in a wi'dow assembly for slidably and releasably engaging ed e rails or window sash; to provide inclined portions on the track members for window sashes to facilitate engagement of the window sash therewith; to provide track members in a window assembly which are continually resiliently urged laterally inwardly in the window y to engage the sashes and form an air tight seal ith by a minimum overlap connection with the of the sash; and to provide window sashes that .c readily moved vertically and which can be swung out, or tilted about the upper margin of the sash, which engaged with the Window assembly, and be conrhe foregoin and other objects and advanta s of the invention will be made more apparent as the specification a better understanding of the present invention, ion now is particularly directed to the accompanydrawings, wherein:

2 is a vertical section of the window assembly of RIG. 1, with portions of the SQSJS being broken away; FIG. 3 is a fragmentary horizontal section taken on lines 33 of FIG. 2 with the upper sash lowered below such line;

FIG. 4 is a fragmentary enlarged section of the sash engaging and positioning means of the window assembly;

PEG. 5 is a broken away vertical section of the window assembly unit of the invention showing the pivotal movement of the window sashes; and

FIG. 6 is a fragmentary horizontal section, like FIG. 4, of the structure as shown in FIG. 5.

When referring to corresponding members shown in the drawings and referred to in the specification, corresponding numerals are used to facilitate comparison therebetween.

This invention relates to a window assembly comprising an upper and a lower sash each having a pair of vertically extending side rails thereon, the lower sash being wider than the upper sash, vertically extending side stiles having laterally inwardly open channel portions therein, a track having a pair of parallel laterally inwardly open sash engaging recesses thereon received in each of the side stiles for lateral movement in the channel portion thereof, and compressible means positioned in the channel portions and urging the tracks laterally inwardly, the sashes having laterally extending pivot pins extending therefrom and engaging said track recesses, the tracks engaging the sash side rails to position the sashes for controlled sliding and pivotal movement but being movable laterally outwardly to compress the compressible means and permit removal of the sashes, the tracks each having laterally narrow shoulders thereon for engaging the sashes in the window assembly but also to facilitate removal, or pivotal movement of the sashes.

Attention now is particularly directed to the details of the st .rctures shown in the accompanying drawings, and a window assembly of the invention is indicated as a whole by the numeral 3. The window assembly it is adapted to be attached to a suitable building 2 and it normally forms a storm, or auxiliary outer window assembly therein.

The window assembly 1 includes a pair of vertically extending side stiles 3 and 4- that are suitably secured to the building 2. The side stiles 3 and i may be made from suitable material and preferably are made from extruded metal, such as aluminum, so that the special contours and shapes shown can readily be formed in the side stiles for receiving and positioning components of he window assembly therein. The side stiles 3 and 4 each have a laterally inwardly open channel portion 5 provided therein, and resilient means, such as a foam rubber or polynrathane, or some other type of a compressible plastic strip body 5 is received therein. This foam or cellular plastic body a in its normal uncompressed form, substantially fills the channel portion 5 in the side stiles and usually extends the length thereof. The side stiles 3 and each have an axially other leg that terminates in a reversely extending stop or flange 7 and an axially inner leg that has an axially outwardly extending short flange 8 thereon for purposes described in detail hereinafter.

So as to position an upper and. a lower window sash 9 and iii, respectively, in the window assembly, a track member ll is received and retained in the laterally inner section of each of the channel portions 5. The tracks are of such a width as to engage the stops '7 and provided. integrally with the side stiles 3 and iat the margins of the channel portion 5. These track members 3.1 may be, made from any suitable material, and preferably are formed from relatively light gage, low friction, substantially rigid plastic material so that the track members have some longitudinal flexibility even though they are provided with sash engagin means, such as pairs of opl3 posed, laterally inwardly open recesses 12 and 13 usually formed by laterally outwardly extending U-shaped ribs 14 and in the track. These recesses 12 and 13 are adapted to engage and slidably and pivotally position the sashes 9 and lib by engaging a pivot pin .or rod it) usually formed'integrally with the upper sash. rail 17 of the upper sash 9, and a pivot pin or redid usually formed integrally with the meeting rail 19 ofthe lower sash 1d. PEG. 4 of the drawings shows that the rods 16 and 1% project laterally beyond the remainders of the sashes, and that the upper sash is narrower than the lower sash, for the reason set forth hereinafter.

The track 11 naturally is made of proper size and shape so as to be complementary to the shapes and sizes of the upper and lowersashes 9 and lid, respectively, to the channel portions 5. Hence the axially inner recesses 12 and the ribs 14 defining such recesses are spaced laterally further apart than the corresponding reccesses '13 and 15 which are of proper size so as to receive the ends of the rod or pin 16 provided on the upper marginal member of the sash 9. As the recesses 12. are laterally outwardly ofiset with the relation to the recesses 13, a generally L- shaped connecting section 2% is provided on the track 11 intermediate these recesses 12 and 13 to form the connecting means extending therebetween. Usually the rods or pins 16 and 18 extend substantially the full depth of these recesses 12 and 13, as indicated in the drawings, whereby a good sliding engagement, as well as a pivotal connection, is established beween the sashes 9 and MB and the tracks 11, as described hereinafter in more detail. 7

It will be seen that the resilient member 6 is made of such size and volume as to normally urge the tracks 11 outwardlyin a resilient manner. The tracks 11 are also adapated to engage the vertically extending members, or siderails 21 of the sashes Q and 1th by flat sections 22 and 2.3 formed in the tracks adjacent the axially outer portions of each of the recesses 12 and 13, respectively, as shown in the drawings. Corresponding fiat sections 24 and 25, FIG. 4, are provided in the tracks 11 by novel and important means of the present invention and which comprise axially outwardly directed, laterally narrow shoulders 26 and 27 formed in each of the tracks. These shoulders 26 and 27 are adapted to engage the axially inner corners or edges of the side rails 21 on the window sashes 9 and 10 and provide substantially air tight, or sealed connections therewith. The flat sections 22 and 23 and 24 and 25 likewise resiliently engage the sides of the sashes to aid in providing sealed slidable connections between the sashes and positioning means so that the sashes can have controlled vertical sliding movement in the window assembly of the invention. The pins 16 and I? are received in the recesses 13 and 12, respectively, and are so spaced from the shoulders 27 and 26 as to aid in obtaining a'good tight engagement of the sashes with the shoulders.

j wardly or axially inwardly in the window assembly be-' It will berecognized that the positioning of the tracks 11 in a resilient manner permit laterally outwardly directed forces to be applied to the tracks whereby the sashes 9 and 10 can be relatively easily released from the shoulders 26 and 27 and be pivotally swung axially inwardly of the window assembly} about the pivot rods 16 and'18 of the sashes. Naturally when one starts such pivotal action, the lower sash 10 is swung outwardly first, and then the upper sash 9 is lowered at least slightly ver-.

tically in the window assembly to free it for pivotal ac-.

tion so that is can be swung out forwardly, or axially inwardly of the window assembly, when desired.

The drawings also show thata screen 28 is provided in the assembly and normally is positioned in the same verfore the upper sash can be lowered. However, it will be realized that the screen 28 may be omitted from the assembly when desired. I

if more than justpivotal movement of the window sashes is desired, it will be realized that additional laterally outwardly compressive forces applied to the tracks 11 will permit atleast one of the pivot rods or pins 16 or 18 to be sprung out of engagement of the tracks 11, afterwhich the entire sash can be removed from the window assembly.

Reassembly of the window sashesinto the units is obtained substantially automatically, particularly when the pivot rods 16 and 18 are-still engaged with the tracks. Such action is obtained by individually swinging the different sashes, and first the uppersash 9, axially outwardly of the window assembly on the rod 16. This will bring the side rails 21 of the upper sash into engagement with diverging portions 30 provided on the tracks 11 between the recesses 12 and 13. The sash 16, when swung up towards a vertical position about the rod 18, contacts diverging or wedging surfaces 359a on the tracks 11 to force them outwardly until the sashes 9 and ltl can snap in behind the shoulders 26 and 27 provided on the tracks. Should the entire sash be removed from the assembly, then one must thread one end of the rod 16 into engagement with a recess 12 andthen exert laterally outwardly directed forces on probably both of the tracks 11 to snap the other end of the rodlo into engagement with its associated recess 12. Then the remainder of the sash can readily be snapped into position.

It will be realized that the sashes 9 and 10 may be of the same or different vertical heights and that they may have any suitable latches, screen means, or other members associated therewith, as desired.

When referring to axially inner and axially outer portions of the window assembly], the surface provided adjacent the inside of the building 2 in which the window assembly is positioned is considered the axially inner surface. I

It will be realized that the securing, or pivot pins or rods 16 and 18 provided on the window sashes usually will be formed integrally with the sash rails with which they are associated, as such sash rails normally are made from metal as extrusions ofsuitable materials, such as aluminum. Such pins or rods 16 and 18 are narrower in diameter than the thicknesses of the sashes which are provided with parallel vertically extending sash or side rails 21 with flat lateral surfaces thereon that will engage with the flat positioning portions of the tracks 11 in the window assembly for sliding engagement and support action thereby.

While the drawings show that thetracks 11 are positioned in engagement with the stops 7 and flange 8 of the channels 3, or side stiles in the assembly, such tracks may be pushed slightly laterally outwardly when the window sashes and 14 are operatively positioned therein. However, the entire window assembly can be initially formed to posi ion the tracks in the manner shown in FIG. 3, for example, when the window sashes will snugly engage with the corresponding portions of the tracks 11 in the manner indicated in the drawings and provide the desired air tight or sealed fit between the vertical margins of the sashes and the associated track means. I

It particularly should be noted that the shoulders 26 j and 27 are quite narrow in a lateral direction, for example, about of an inch,.so that only a slight pressure need be applied to the track in order to spring margins of the sashes out of. engagement with the shoulders. At the same time, the right angular relationship between these'shoulders and the associated flat portions in the strips provide a secure positioning of the sashes for sliding action and at the same time furnishes the desired sealed connection or positioning of the sash. Window assemblies built in accordance with the principles of the invention have been tested to show that very satisfiactory sealed, sliding positioning of the sashes is obtained.

it will be realized that in some instances the provision the pivotal action of these window sashes may not be sired in order to produce securely positioned, but readily By the use of the pivotal means shown, it is more convenient to handle the sashes for cleaning action, for example, without completely removing them from the window assembly. Hence, a well positioned, easily controlled, sash is provided in the window assembly.

it should be noted that the la orally inwardly extendng portions of the connecting sections in the tracks ircduce rear stops against which, or past which the lower sash cannot move axially outwardly in the window assembly. wise, the stops '7 provided on the side stiles 3 and ll prevent any axially outward mov eat or the upper sash when positioned It be re tion may be made th se tracks can be p .cncd for lateral outward movement in the window ass: "ly by any suitable means so long as such tracks are resiliently urged laterally inwardly in the window assembly.

While the window assembly of the invention is shown extending in a vertical direction, it extend laterally, if desired. lrence terms such as upper and lower sash are also meant to include left and right sashes having horizontal slic' g action.

From the foregoing it will be seen that a novel and improved type of a window sash and positioning means therefor has been provided a window assembly. This window sash can be provided with controlled pivotal .tovernent in the ass bly, when desired, for cleaning or other action, or the tire sash can be eadily removed therefrom, as desired. in all events, the window will have a sealed sliding engageaent with its positioning means but because of the relatively narrow lateral overlap provided between axially inner portions of the window positioning means and the window sash, such sashes can be conveniently and readily disengaged from their posilionlng tracks. Hence it is believed that the objects of the invention have been achieved.

While one complete embodiment of the invention has been disclosed herein, it will be appreciated that modificalion of this particular embodiment of the invention may be resorted to without departing from the scope of the invention as defined in the appended claims.
